Beit known that we, JOHN W. BARNETT and MORTON SANDERS, citizens of theUnited States, residing at Monmouth, in the county of lVari-en and Stateof Illinois, have invented a new and useful Marking Attachmentfor Corn-Planters, of which the following is a specificatio'n.

This invention relates to land markers, such as are used,.for instance,in connection with corn-planters for the purpose of laying out ormarking the land as the machine progresses for the purpose of guidingthe driver or operator upon the return trip; and it has I 5 for itsobject to simplify and improve the con- The operators or struction andoperation of this class of deported upon a tripod, two members of which,vices. 15, are connected with the side members of With these and otherends in view, which the wheel-frame, the third member being exwillreadily appear as the nature of the intended forwardly and connectedwith the shaft vention is better understood, the invention 4, upon whichthe hand-lever is fulcrumed. consists in the improved construction andThe seat-supporting member 16 has a quadnovel arrangement andcombination of parts, rant 17 attached thereto for engagement with whichwill be hereinafter fully described, and a stop member 18, connectedwith the handparticularly pointed out in the claim. hand-lever 5, whichlatter may be thereby re- 5 In the accompanying drawings has been tainedat various adjustments.

Upon theside members of the wheel-frame Corresponding parts in the severalfigures 1, near the rear end of the latter, is supported are indicatedthroughout by similar characa cross-bar 25, which is connected with saidters of reference. side members by means of hook-bolts 26 and he mainframe or wheel-frame 1 of an ornuts 27. The cross-bar carries anapproxidinary corn-planter has been shown as being mately semicirculararch-bar 28, which may provided upon the sides thereof with bracket beconstructed of round iron, the ends theremembers 2 2, supporting attheir lower ends of being firmly attached to the cross-bar 25. the shaftor axle 3 and at their upper ends a The rear cross-bar 29 of the frame 1has been transverse shaft 4.

The stud 32 has ahead 35, which is provided with a slot 36, in which is pivoted themarker-stat? 37, which latter is provided at its outer end with aground-engaging shoe 38, which may be of circular form, as shown in thedrawings, although any suitable form of shoe will answer the purposes ofthe invention. Suitably connected With the fixed point of themarker-staff is one end of a chain 39, the other end of which has a ringor link 40 loosely engaging the arch-bar 28. Likewise connected with themarker-staff at or near the point of attachment of the chain 39 is oneend of a flexible member {LL which is guided over the pulleys 22 and 23,the free end of said flexible element being attached to the rod 20 nearthe front end of the latter or to any other suitable fixed point. ousthat the flexible member 41 is to be of such a length that it may serveto support the marker in ground-engaging position when the corn-planterwith which it is connected is traversing the field.

When the machine is to be turned at the end of the row, the hand-leveris manipulated to elevate the rear end of the tongue, together with therunner-frame, thus depressing the rearward-extending arm 7 andmanipulating the flexible element 41 so as to elevate the marker-staffto the position shown in dotted lines in Fig. 1, thus enabling themachine to be turned and placed in position for the return trip, when byagain manipulating the hand-lever 5 the tongue and the runner-frame willbe restored to operative position. The same will be the case with themarker-staff, provided that the first operation of the lever 5 wasaccomplished with sufficient force to swing the marker-staff across itspivotal center; if not, it may be found necessary for the operator tomove it slightly by hand in order to cause it to descend at the properside of the machine. The chain member 39 by engaging the arch-bar 28 notonly marker-staff with relation to said arch-bar, but its length mayalso be so adjusted as to It is obviserves to guide the I support themarker-staff in operative position, thus at all times relieving theflexible element 41 of the strain caused by the weight of said bar.

The marker-staff 37 being connected pivotally with the supporting-pivot32 at an angle to the axis of the latter will at all times swing clearof the drivers seat, its movement with relation to the planter-framebeing practically of a universal character.

This invention, as will be seen from the foregoing description, issimple in its nature, and it may be easily and effectively applied tocheck-row corn-planters of ordinary construction.

Having thus described the invention, what is claimed is- Aplanter-frame, a seat-supporting tripod upon said frame, a cross-barconnecting two of the seat-supporting members, a bracket connected withthe third seat-su pporting mem her and extending rearwardly through saidcross-bar, a quad rant securely connected with one of theseat-supporting members, a handlever supported concentric with saidquadrant and having a stop engaging the latter and a rearward-extendingarm, a marker-staff connected pivotally with the ley supported at thefree end of the bracket member, a flexible member connected with themarker-staff and guided over said pulley to a fixed point of attachment,and a guide-pulley connected with the rearward-extending arm of thehand-lever and engaging said flexible element intermediate theguide-pulley at the free end of the bracket and the fixed point ofattachment.

In testimony that we claim the foregoing as our own we have heretoafiixed our signatures in the presence of two witnesses.
